Hello! I'm new to this site, thought I'd ask some knowledgable people.
I have a Weil-McLain Ultra 230 hot water heater and house heater, running on propane. Lately I've been getting b 25 errors when it starts up, and the occasional hard e 36. I restart as they suggest, giving 10, 11, 12, etc. minutes between restarts, and it eventually does. But what could the problem be? I'm guessing the system needs bleeding and air is slowing inflow, making outflow too hot too fast. Or is there a filter somewhere that needs changing? Or just a bad sensor? Any pointers to previous discussion and how a relative newbie can fix it himself would be great!
